REVERSIBLE PLOW.

SPECIFICATION forming part of Letters Patent No. 769,167, dated September 6, 1904.

' Application filed June 25, 1908. Serial No. 163,074. (No model.)

To all whom, it may concern: I

Be it known that I, WILLIAM GAsToN- J01;- LING, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented new and useful Improvements in Reversible Plows, of which the following is a specification. 4

This invention relates particularly to .reversing disk plows of that class in which the plow is reversed by swinging the tongue to which the draft-animals are attached without turning the wheeled frame of the plow.

An objectof the invention is to improve the means whereby the disk is reversed by the swing of the tongue.

A further object of the invention is to produce improved means whereby the furrowwheels will be equalized or adjusted angularly with respect to the line of draft by means of the swing of the tongue. I

A further object is to produce an improved land-wheel which will adjust itself to the angle of draft. I

A further object is to improve the swivel ing journal-boxes of the crank-axles of the furrow-wheels so that they may take the required draft adjustmentwithout affecting their vertical adjustment.

A further object is to produce means for automatically swinging the disk-scraper when the disk is reversed.

With these andfother objects in view the invention is hereinafter described, and is illustrated in the accompanying drawings, in

Referring now specifically to the drawings,-

I 1 indicates the main longitudinal beam, which joined to or cast with a semicircular plate 2,

may be made tubular or otherwise. This is projects.

grooves in the bearing.

projecting substantially horizontally on the land side of the beam. The tongue 6 is pivoted at 6* upon this plate and is adapted to swing around horizontally to reverse the plow. From the other or furrow side of the wheel a substantially horizontal wedge-shaped lug 3 This is cast on the frame 1 and supports the reversing attachment, (indicated at 7.) This comprises a hollow wedge-shaped casting whose hollow 7 a is shaped to fit over the wedge 3, but is of greater width or angularity, so that the casting is free to swing horizontally until one of the sides thereof contacts with the side of the lug, the casting being pivoted upon the lug by a bolt 7 at the point of the wedge. The width or angularity of the wedge-shaped lug may be varied by removable pieces 3, bolted to the sides of the lug, as shown in Fig. 6, whereby the width of the furrow is regulated or wear taken up.

At the rear or base of the wedge-shaped casting 7 is a pin 27, which projects vertically through a segmental slot 28 in the rear end of the tongue. When the tongue swings around,

the pin strikes the end of'the slot and turns the casting 7 on its pivot 7 accordingly, which has the effect of reversing the disk. The same effect is assisted or produced by crossed chains 40. These are connected at one end to oppositesides of the casting 7 and are then crossed and passed around rollers 40 on the top of the beam and joined by rods 30 to the whiffletree 30*. When the tongue is swung around, the respective chains will cause the casting to swing around to the other side and reverse the plow. Either the slot-and-pin arrangement or the chains, or bpth, may be used to effect the reversal of the p ow.

The casting 7 carries the bearing-box 7 c of the disk-holder 33, the disk attached thereto beingindicated at 10. The stem of the diskholder has a rib 33 around it, which fits in The lower bearing is cast solid with the box 7 but the upper bearing 33 is removable and adjustable by means of the set-screw-34 behind it, so that the wear can be taken up.

The disk-scraper is indicated at 9 and is v beam 1.

carried at the outer end of a spring-arm 11, which works in notches at 8 upon the top of the casting 7. The scraper-arm 11 is bolted to the top of the casting 7 by a pivot-bolt, and the inner end thereof projects into the path of studs 29 on the end of the tongue. When the tongue swings, one or the other of the studs strikes the scraperarm and shifts the same into one or the other of the notches 8 to throw the scraper across the face of the disk in the right position to work when the plow is reversed.

The furrow-wheels are indicated at 17 and rotate upon crank-axles 15, which are carried in swiveling brackets 13 at the ends of the The brackets swivel horizontally on hubs or bosses 1 1 at the ends of the beam, through which the pins 13 of the brackets extend. Each bracket is also formed integrally with a segment-rack 16. The levers 18 to turn the axles to raise or lower the plow are fixed to the axles inside the brackets and have the usual spring-catches 19, which engage the segments to fix the plow at the desired height. A combined swiveling bracket and segment is thus produced, which is very effective for the purpose intended. The extended inner ends of the crank-axles 15 are connected by an equalizing-rod 23 for adjustment of the furrow -wheels to the line 'of draft. This rod carries adjustable collars 25, which are properly positioned to be engaged by the studs 29 when the tongue is shifted. The studs strike the collars and throw the wheels and axles accordingly. The proper lead is secured by adjustment of the collars 25.

The land-side wheel 5 is carried on an axle 4:, which is pivoted to the plate 2 conveniently by the same bolt 6 as the tongue. The axle is free to swing laterally between lugs 81 on the botton of the plate 2, at the outer edge thereof, so that the Wheel will take the proper direction of draft. The landside of the plow may be raised or lowered by means of a bolt 32, which is vertically adjustable in a series of holes in the lugs.

In operation the plow may be run back and forth Without turning thebody and wheels around by simply swinging the tongue on its pivot, which will have the eifect of throwing over the casting or attachment 7 which carries the disk, thereby reversing the plow. As said before, this result may be effected by either the chain or the slot-and-pin construction, or both. The swing of the tongue also throws the scraper across the disk to the proper position and changes the lead of the furrow-wheels accordingly. The land-side wheel takes its proper position when the plow is started.

What I claim as new, and desire to secure by Letters Patent, is

1. In a reversible plow, the combination with the beam having a rigid wedge-sha wd lug projecting therefrom, of a plow -support pivoted to the lug and abutting against one or the other of the sides thereof, a reversible tongue, and means actuated thereby to turn the support.

2. In a reversible plow, in combination, a beam having a rigid wedge-shaped lug, a plowsupport pivoted at the point of the lug and having angular faces adapted to contact with the sides of the lug, and a reversible tongue engaging the support and acting to reverse the same.

3. In a reversible plow, the combination with a wheeled beam, of a plow-support pivoted thereto, tongue-actuated means to reverse the same, and an immovable abutment carried by the beam, having opposite faces against either of which the plow-support abuts.

4. In a reversible plow, the combination with a wheeled beam, and a reversible tongue pivoted thereon and having a curved slot at the rear end, of a plow-support pivoted on the beam and having a pin 1 )rojecting into the slot, to reverse the plow when the tongue is reversed.

In a reversible plow, the combination with a wheeled beam, and a reversible tongue pivoted thereon, of a reversible plow-support pivoted on the beam, and crossed chains connected to the tongue and the support, to reverse the latter when the tongue is reversed.

6. In a reversible plow, the combination with a beam and a reversible tongue pivoted thereto, of swiveling furrow-wheels connected by an equalizing-rod, adjustable collars on the rod, and projections carried by the tongue, adapted to strike the collars and throw the wheels.

7. In a reversible plow, the combination with a wheeled beam having a wedge-shaped abutment thereon, of a reversible plow-support having a hollow of greater angularity than the abutment and fitting thereover, a pivot-bolt connecting the abutment and the support, and a reversible tongue engaging the support to reverse the same.

In testimonywhereof I have signed my n amc to this specification in the presence of two subscribing witnesses.
